We have this amazing plugin running now with Jochem's fix on two development sites, one at bluehost and the other at Media Temple. Everything works great.
But, on another production site at MT, it is not sending the mail. Any guesses what environment variables would prevent the mail from going out? I have tested php mail and wp-mail separate from the plugin and they both work fine.
Also, is it possible for one of us to post the fixed version to the SVN repo so others can download a working copy. Or to make the post with the fix in it a sticky post at the top of the list with a more appropriate title.
This is a one of a kind plugin.
